Step 2:
Select a location to mount the junction box for the AV7900 units. Normally the junction box is best
located under either the driver or passenger seat. Be sure to locate it so that it will not obstruct any moving
parts in the seat or damaged by the feet of passengers.

Step 3:
Route the power harness to the dash area where you have located the 12V (+) ACC connection
point. Be sure to protect the cable from any potential sharp edges which could damage the harness in the
future. To avoid vibration noise, use tape to secure the harness whenever possible.
Step 4: Route the FMT antenna wire (purple) toward the antenna/tuner. (Be sure to separate it
from the power wires and avoid any power seat modules or other vehicle harnesses as these
may induce noise into the FM transmission.)
Step 5:
When connecting the power harness, Rosen recommends soldering all connections. When using
T-Tap or crimp connectors, always ensure the connections are made with the proper gauge connectors.
Failure to make a proper connection will result in a system failure in the future.
Step 6: With ACC off, plug all harnesses into the main interface unit. Note: Plug the main power
harness in last.
